Inside "Branching options" for "Custom end scenario" choice rename:
"Customize end scenario" to "Feedback on the end screen"
"Custom end scenario title" to "Feedback title"
"Custom end scenario text" to "Feedback text"
"Custom end scenario image" to "Feedback image"
Inside "Branching options" make both "Feedback on the end screen" and "Feedback" groups expanded by default
To improver: Text is just changed in the code as it is hardcoded. Separate issue for moving all text to l10n is added.
I wasn’t able to test feedback groups expanded by default as I’m not sure how to show this find this setting but the first changes are done.
